WHat should I do about my landlord?

I have a one year lease with them. There is mold growing on the wood work around the windows that we are allergic to ( I have 2 babies and it grows in their bedroom and mine). Their dog leaves poop all over the yard and they clean it up rarely. In the lease it clearly states that it is their resposibilty to shovel snow in the driveway, yet they made my husband and I do it last winter on our side of the driveway. They were irrate when we did not do it, and they blaimed us becuase the garage door broke because of the ice built up under it. They hit our car (which at the time was a peice of junk, but still), they told me but did not offer to fix it, or give us insurense info., or any kind of compensation. i have asked them so many times for rent reciepts fr the past 3 months because we paid in cash, but they have not given me anything. Seeing as ow i have 2 babies, i get a little backed up on laundry sometimes. I was about 7 or 8 loads behind last month and she told me i had to go to the laundromat and do it, even though we have a washer and dryer provided for us in the home, which is also part of the lease agreement. She unplugged our internet becuase she was "unhappy" with us, even though we were told it was provided for us when we moved in (not in the lease unfortunetaly). Their son shoots hockey puck into the wall in the basement which is directly below our livingroom and bedroom. it is so loud and wakes my children up. He also does it during dinner time. They leave their dog in a kennel when they leave for hours and the walls are paper thin, so we hear her barking and yelping the whole time they are gone. Please let me know if you have any suggestions, because I am not sure what to do. Thanks in advance.
